Lecture hall and seminar building, Salzgitter

The agn design for the new lecture hall and seminar building provides the Ostfalia Campus (formerly Braun-schweig/Wolfenbüttel University) with a new entrance and a logical addition. The orientation and the architecture of the new building orient themselves on historical coal mine structures. From the outside, the three-storey building has a very compact appearance; the interior is very differentiated thanks to the ample light, configured flights of stairs, lecture hall and video studio cubicles as well as galleries. The usage volumes are inserted into the three-storey new building in a way that creates a light-filled interior with central function. The library's self-contained area takes up the northern part of the ground floor; the lecture hall with attached laboratories are also arranged on the ground floor. The seminar rooms and offices in both upper stories surround the inner laboratory and service rooms and are grouped according to their function. The comprehensive design's central element is the energy concept with an optimized building envelope and use of geothermics via ground piles and thermal registers. The project is a model for the Lower Saxony's Energy Efficient University Projects Program, funded by the German Environmental Federal Fund (DBU).
